Novel approaches are devoted towards creating 3D scaffolds that allow good permeability and diffusion. Appropriate synthetic biodegradable materials for this purpose are biopolymer- bioceramic nanocomposites. They have good tissue compatibility and safety profiles seem essential for their successful utilization in medical applications. The 3D dicalcium phosphate/dextran/ sodium carboxymethyl cellulose nanocomposites are prepared by freeze-drying method. In the present work, the physico-chemical properties of scaffolds are evaluated by XRD and FTIR. The interior morphology as well as porous structure are evaluated by scanning electron microscope (SEM). The porosity of scaffolds examined by mercury intrusion porosimetry (MIP). In addition to compressive stress parameter is also determined by Instron Industrial Product,(Model 3345;Norwood, MA, USA).The respective nanocomposite scaffolds are tested for in vitro Hepg2 cancer cytotoxicity. The nanocomposite scaffolds exhibit good biocompatibility and exerts no toxic effect on Hepg2 liver cancer cell. Therefore, the prepared porous system of nanocomposite scaffolds can be considered as promising technique for tissue engineering.
